when i do the deployment, i changed the app.config file.
'isDistributed' is set into 'true', remoteBaseURL is set into
"http://dragon.factory.lan". then i build the solution and generate the
file set for server side and client side, also add all the required DLL files. now, the server side runs
properly and it's waiting for request, but my client side couldn't run
at all, every time it crashes. what's the problem? i only made 2 modification on the config files, isDistributed and remoteBaseURL, all others are the default values.  |

Well, we need a little more information.
- How are you hosting the server - IIS, ServerConsole, ServerService?
- Is the server on the same machine as the client?
- Can you ping that remoteBaseURL from the client (using ping from the command line)?
- What is the error you receive on the client? Check its debuglog for more info.

Hi kimj, I set up the project for monkeyking so I can answer these implementation questions. A ServerConsole is running on a separate machine. It claims to be listening: >ServerConsole.v4.exe Trying programmatic configuration of EntityService using ideaBlade.v4 section Listening on http://dragon.factory.lan:9009/EntityService Listening on http://dragon.factory.lan:9009/ Press <Enter> to end publication. and indeed it is. I am able to connect to it using netcat, ping, and by browsing to http://dragon.factory.lan:9009/ Service This is a Windows© Communication Foundation service. Metadata publishing for this service is currently disabled. If you have access to the service, you can enable metadata publishing by completing the following steps to modify your web or application configuration file: 1. Create the following service behavior configuration, or add the <serviceMetadata> element to an existing service behavior configuration: The client error: {"Exception has been thrown by the target of an invocation."} Which seems to indicate it's missing something. UPDATE: I managed to find the inner exception, "Unable to start the EntityServer service" . This is pretty self explanatory, the client is trying to start the application that resides on a separate server. We'll look at the client code and convince it otherwise. Here's a file listing on whats on the client. -rwxrw---- 1 jzhai domain users 2429 Apr 30 12:31 DebugLog_1.xml -rwxrw---- 1 jzhai domain users 399 Apr 30 12:29 DebugLog.css -rwxrw---- 1 jzhai domain users 3267 Apr 30 14:58 DebugLog.xml -rwxrw---- 1 jzhai domain users 3123 Apr 30 12:29 DebugLog.xsl -rwxrw---- 1 jzhai domain users 141824 Apr 30 14:43 DomainModel.dll -rwxrw---- 1 jzhai domain users 159232 Apr 30 14:43 GUI.exe -rwxrw---- 1 jzhai domain users 798 Apr 30 14:44 GUI.exe.config -rwxrw---- 1 jzhai domain users 86016 Mar 2 14:44 IdeaBlade.EntityModel.Server.v4.dll -rwxrw---- 1 jzhai domain users 380928 Mar 2 14:44 IdeaBlade.EntityModel.v4.dll -rwxrw---- 1 jzhai domain users 67072 Mar 2 14:44 IdeaBlade.Linq.v4.dll -rwxrw---- 1 jzhai domain users 49152 Feb 23 14:37 IdeaBlade.UI.dll -rwxrw---- 1 jzhai domain users 65536 Feb 23 14:37 IdeaBlade.UI.WinForms.dll -rwxrw---- 1 jzhai domain users 274432 Mar 2 14:44 IdeaBlade.Util.v4.dll -rwxrw---- 1 jzhai domain users 75776 Mar 2 14:44 IdeaBlade.Verification.v4.dll -rwxrw---- 1 jzhai domain users 22528 Apr 30 14:43 Presentation Spirit.dll -rwxrw---- 1 jzhai domain users 23040 Apr 29 12:34 Presentation Spirit.exe The developers guide seems to indicate these are the required libraries, as instructed on p449 in the guide. Thanks for your help, Dallas |

There are unfortunately a myriad of reasons why a client won't be able to connect to the server. When the client does make the attempt, we should see tracing messages in both the client-side and server-side debug logs which may help us understand the issue. So, if you could post these or send to support that will help. Please also post or send your .config files for both client and server. Check your firewall software to ensure that the port (9009 in this case) is open on both the client and server. Firewall issues are a frequent cause for communication failures.
Your client-side file list looks OK, although you don't need IdeaBlade.EntityModel.Server.v4.dll - that's needed server-side only when you run n-tier.
